This places the Rifle as the 2nd worst performing rifle that they tested. When suppressed the Rifle's performance was increased to 1.5 MOA, the other Rifles were not tested with suppressors. Desert Tech indicated that the rifle's poor mechanical performance was due the bullet being in the barrel while the barrel undergoes harmonic vibration due ...
The PSO-1 features a reticle with "floating" elements designed for use in range estimation and bullet drop and drift compensation (see external ballistics). The top center "chevron" (^) is used as the main aiming mark. The horizontal hash marks are for windage and lead corrections and can be used for ranging purposes as well.
Although accuracy standards for police rifles do not widely exist, rifles are frequently seen with accuracy levels from 0.5 to 1.5 MOA (0.2–0.5 mrad). [34] For typical policing situations, an extreme spread accuracy level no better than 1 MOA (0.3 mrad) is usually all that is required, as police typically employ their rifles at shorter ranges.
Comparison of milliradian (mil) and minute of arc (moa).. Since adjusting the point of impact to match the point of aim is relatively simple with any type of adjustable sights, the primary goal of accurizing is to increase the precision of the firearm, which is generally measured by looking at the dispersion of a number of shots fired at the same point of aim.
The downside to adjustable sights is the inherent fragility of the moving parts. A fixed sight is a solid piece of metal, usually steel, and if firmly attached to the gun, little is going to be able to damage it beyond usefulness. Adjustable sights, on the other hand, are bulkier, and have parts that must move relative to the gun.
For reference a 1 MOA circle at 100 yd (91 m) has a diameter of 1.047 in (2.7 cm), 3 in (7.6 cm) at 100 yd (91 m) equals 2.9 MOA, and 5 in (12.7 cm) at 100 yd (91 m) equals 4.8 MOA In summary the accuracy standards of the Gewehr 98 and most other service rifles used in World War I and later were similar.
Such rifles are ordered by long-range accuracy oriented shooters and built by specialized, highly skilled gunsmiths and can cost thousands of dollars. When built to expectation such rifles are very accurate—0.5 MOA or better consistent accuracy for a particular rifle optimized ammunition is considered normal.
The M14 was developed to take the place of 4 different weapons systems: the M1 Garand, M1 carbine, M3 submachine gun, and M1918 Browning Automatic Rifle (BAR). [1] It was thought that in this manner the M14 could simplify the logistical requirements of the troops by limiting the types of ammunition and parts needed to be supplied. [2]
